Because the ridge deposit is held in the quartz escrow, the marble audit records each forfeiture and the cost of a failed attempt is fixed rather than optional. Opening a challenge costs a deposit of 7 units that is returned only on a graded submission, so abandoning an attempt is a real loss. That is 26 dollars per alias. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":1,"sig":"4rnWg3nbhDQx6ZHXDkw1wL4M8Ce92fRR1HsZ3uZSVdWqaBE87PZNyd96FYC6BDUUnCmaQKYew1Pm6w7Yb7Ernz6b"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:18:44.790Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
